The Night In Question by Kathleen Glasgow - Trade Paperback - Teens Fiction

Alice Ogilvie and Iris Adams became the talk of Castle Cove when they cracked the biggest case of the fall: the death of Brooke Donovan. Together, the Agathas put Brooke's killer away for good, and since then things around town have been almost back to normal. Quiet, even.

But if Alice and Iris know anything, it's that sometimes quiet is just the calm before the storm. The truth is, Brooke's disappearance wasn't the first mystery to rock Castle Cove, and it won't be the last. So when their school dance at the infamous Levy Castle—the site of film starlet Mona Moody's unsolved death back in the 1940s—is interrupted by a violent assault, Iris and Alice pull out their murder boards and get back to work.

To understand the present, sometimes you need to look into the past. And if the Agathas want a chance at solving their new case, that's exactly where they'll need to start digging. Only, what they uncover might very well kill them.
